Problem 13-9 - In this problem you are to determine when the existing drill press (the defender) purchased two years ago for
$40,000 should be replaced by the new drill press (the challenger) having the uniform annual cost (UAC) of $7000. The yearly cost data for the defender are available in the problem and tabulated in the table in part (a). Solve this problem by completing the marginal cost table and answer questions below.
a) Complete the marginal cost table of the defender below (ref. Example 13-3 and 13-4)
